UPSC Exam Analysis
A lot of candidates make the mistake of thinking that once they are done with the UPSC syllabus, and solving mock tests, they are ready to crack the exam. But let me be the one to break this to you.
That’s not enough! As long as you have not thoroughly analyzed the previous year’s exam papers, your job is only half done.
One of the most important aspects of a successful UPSC preparation is to analyze the past year’s exam papers.
Doing so will render you with a greater understanding of the most important topics from which questions are usually asked in the exam, and also the difficulty levels of the various sections in it.
That said, I have provided my students with a detailed exam analysis of the Commerce and Management past years’ exams. You’d do good to check it out.
However, you might have the question of why I have not made the exam analysis of past exams of the other subjects, well the answer to that is, they are still in the pipeline. I’ll let you know as soon as I am done with them.
But for now, you can go through UPSC exam analysis of the Commerce & Management from 2020 – 2023 which I have comprehensively provided. Do so by clicking on the linked blog.

The UPSC Cutoff is one of the most discussed aspects of the Civil Services Examination (CSE). Understanding it is essential for succeeding in your preparation and expectations accurately.

- Prelims Cut-Off: Only marks from Paper I (General Studies) are considered. Paper II (CSAT) is qualifying in nature; you need to score a minimum of 33%, but it does not count towards the merit cut-off.
- The cut-off is subject to 10% marks in each of the seven competitive papers that are Essay, GS-I, GS-II, GS-III, GS-IV, Optional-I and Optional-II.
- The cut-off for each stage represents the minimum marks secured by the last candidate who qualified for the next stage (or for final selection).
- UPSC releases the Prelims and Mains cut-off marks only after the final result of the CSE is published.
